Steganography is the art and science of hidden (or covered) communication. In digital
steganography, the bits of image, video, audio and text files are tweaked to represent the …

This paper presents a new efficient embedding algorithm in the wavelet domain of digital
images based on the diamond encoding (DE) scheme. Current discrete wavelet transform …

Steganography represents the art of unobtrusively concealing a secret message within
some cover data. The key scope of this work is about high-capacity visual steganography …

Due to the 3D spatiotemporal regularities of natural videos and small-scale video quality
databases, effective objective video quality assessment (VQA) metrics are difficult to obtain …

Image steganography is a technique of concealing confidential information within an image
without dramatically changing its outside look. Whereas vehicular ad hoc networks …

Steganography is the science that involves communicating secret data in an appropriate
multimedia carrier, eg, image, audio and video files. It comes under the assumption that if …

Building a balanced relation between image quality and the payload, the robustness of the
method in facing electronic attacks and securing data, all the mentioned processes …

Now-a-days, biometric systems have replaced the password or token based authentication
system in many fields to improve the security level. However, biometric system is also …

Nowadays, video quality assessment (VQA) is essential to video compression technology
applied to video transmission and storage. However, small-scale video quality databases …

This work proposes a wavelet based Steganographic technique for the color image. The true
color cover image and the true color secret image both are decomposed into three separate …
